Colorless or colored nail polish containing aramide fibers

Abstract

Colorless or colored nail polish contains, in a polish solvent system, a film-forming substance, a resin, a plasticizer, and 0.01 to 0.5 wt. % aramide fibers (poly[paraphenylene terephthalamide]), and provides improved adhesion and strength of the polish on the nails.

What is claimed is: 
     
       1. A colorless or colored nail polish comprising: (a) 55 to 90 wt. % of a polish solvent system;   (b) 5 to 20 wt. % of a film forming substance;   (c) 0.5 to 10 wt. % of a resin;   (d) 2 to 10 wt. % of a plasticizer, and   (e) 0.01 to 0.2 wt. % of aramide fibers where in the aramide fibers are poly(paraphenylene terephthalamide) fibers.   
     
     
       2. Nail polish according to claim 1 wherein the aramide fibers have a length between 2 and 4 mm. 
     
     
       3. Nail polish according to claim 1 wherein the film-forming agent is 1/2 second SS nitrocellulose. 
     
     
       4. Nail polish according to claim 1 wherein, the resins are selected from the group consisting of aryl-sulfonamide-formaldehyde and aryl-sulfonamide-epoxy. 
     
     
       5. Nail polish according to claim 1, further comprising at least one coloring agent of an organic or inorganic nature. 
     
     
       6. Nail polish according to claim 5, wherein the coloring agent is present in a concentration of between 0.01 and 2% relative to the total weight of polish. 
     
     
       7. A colorless base polish conferring a slightly rough appearance by application on the nail and allowing better adhesion of a colored nail polish applied subsequently, said colorless base polish comprising: (a) 55 to 90 wt. % of a polish solvent system;   (b) 5 to 20 wt. % of a film forming substance;   (c) 0.5 to 10 wt. % of a resin;   (d) 2 to 10 wt. % of a plasticizer, and   (e) 0.01 to 0.2 wt. % of aramide fibers having a length between about 2 to 4 mm wherein the aramide fibers are poly(paraphenylene terephthalamide) fibers and, said aramide fibers conferring to the base polish the rough appearance on the nail.   
     
     
       8. The base polish of claim 7, wherein the film forming substance is 1/2 second SS nitrocellulose. 
     
     
       9. The base polish of claim 7, wherein the resin is selected from the group consisting of aryl-sulfonamide-formaldehyde and aryl-sulfonamide-epoxy.
